Hi Edwin, I'm fine.  How about you ?

In this case, XSD is the right way because it is the order itself contains 
multiple line items.  This is part of the document structure and no extra 
complex type need to be created.

Compare this with the other case where the seller need to handle multiple 
purchase orders.  Now without array support in BPEL, you need to create a 
new complex type to represent multiple purchase order.

XSD in its current form is good enough to describe the structure of "a 
document".  I'm not asking for XSD extension to describe "an array of 
document".
